A 400-character caption on Instagram
Instagram shows about the first 125 characters before "…more", so 275 of the 400 are hidden until someone taps. Put the hook in those first 125.
To find Instagram hashtags, type the topic of your post and the Instagram hashtag generator suggests broad, niche and community tags in groups, sized to Instagram’s rules. It works from templates, not live trend data, so search each tag on Instagram before you post and keep the few that match the post best. Instagram posts take up to 2,200 characters, shows about 125 before "…more", and allows up to 30 hashtags.
Type the topic of your post; the suggestions come back in four groups, broad, niche, branded-style and community, so you can pick a few that fit instead of pasting a long list.
Instagram is moving to 5 hashtags per post and Reel — pick the ones that most precisely match the post, not the longest list.
Instagram is moving its apps to 5 hashtags per post and Reel (announced December 2025); Meta’s API allows 30 per caption, the cap SkedCast’s composer checks.
20 suggestions across 4 categories
Umbrella tags for the topic’s niche — structural, not measured volume.
Compound tags built from the exact topic.
A template — swap in your own brand, product or campaign name.
Tags aimed at people who identify with the topic.
Template-based suggestions, not AI, and not real-time trend or volume data — SkedCast has no hashtag-volume API. Research each tag on the platform itself before you use it. Nothing you type here is uploaded or stored; suggestions are generated entirely in your browser.
Five, going forward. In December 2025 Instagram said it would gradually limit the hashtags in a post or Reel caption to 5, down from 30, because fewer, more targeted tags work better. Meta’s API documentation still lists 30 per caption, so the limit depends on where the caption is written:
| Where | Limit | Note |
|---|---|---|
| Instagram app, posts and Reels | 5 hashtags | Announced by Instagram in December 2025, rolling out gradually; earlier the app allowed 30 |
| Meta’s Instagram API (captions) | 30 hashtags | Meta’s API documentation: up to 2,200 characters, 30 hashtags and 20 @ tags |
| SkedCast composer | Up to 30, 5 recommended | Checks the cap before a post is scheduled |

The ones that say most precisely what the post is about. With five to spend, mix the groups: one or two niche tags built from the exact topic, one broad tag for the wider subject, a community tag for the people who follow it, and your own branded tag if you have one. Instagram describes hashtags as a way to tell people what a post is about and to connect related posts, not as a reach lever, so search each tag on Instagram first and drop any that are unrelated or spammy. The hashtag counter checks how many a caption carries, and the Instagram character counter keeps the caption within 2,200 characters.
The limits SkedCast’s composer checks for Instagram before a post goes out, read from the same rules table the composer uses.
| Text limit | 2,200 characters |
|---|---|
| How length is counted | As you see it: one emoji or accented letter counts as one character |
| Hashtags | Up to 30 per post; extras are flagged before publishing |
| @-mentions | Up to 20 per caption; extras are dropped |
| Where the caption is cut off in the feed | About 125 characters before "…more", so lead with the point |
| Text-only posts | Not allowed: every post needs an image or video |
| Links in the text | No link-preview card |
| First comment | Supported: SkedCast can post a first comment right after publishing |
| Feed crop | 4:5 in the feed preview |
| Images | up to 10 per post · JPEG · max 8 MB each · aspect ratio 4:5 to 1.91:1 |

That is 5 over the 30 SkedCast allows for Instagram, so the post is flagged before it publishes rather than going out with tags dropped.
For "vegan bakery" on Instagram, the generator returns 4 categories totaling 20 suggested tags. The "Broad / high-volume style" group alone returns 5: #veganbakery, #foodie, #foodstagram, #instafood.
For "fitness coach" on Instagram, the generator returns 4 categories totaling 20 suggested tags. The "Broad / high-volume style" group alone returns 5: #fitnesscoach, #fitness, #fitfam, #workout.
In SkedCast, write the post once and give Instagram its own version with its hashtags, while LinkedIn or Threads get theirs. The composer counts the hashtags before the post is scheduled, and saved hashtag groups keep your regular sets one click away. See the Instagram scheduler and the hashtag limits by platform, or generate tags for another network with the hashtag generator.
